rockbox/firmware/export/lcd.h
Nicolas Pennequin f3b015f73b FS#7808 by Tom Ross, Ken Fazzone and me, with help from Antoine Cellerier. 
Add two new line selector types: solid colour and gradient. Solid colour only uses the primary colour setting.
The secondary colour setting is used for the gradient. Text colour for the selected item is also changeable.
These new settings are a bit controversial so they may be removed later.
